REFRIGERATOR FOR COOLING LIQUIDS.

Specification of Letters Patent No. 9,813, dated June 28, 1858.

T 0 all whom it may concern Be it known that I, BARNABAS H. BARToL, of the city and county of Philadelphia, State of Pennsylvania, have invented a new and Improved Refrigerator for Cooling Liquids, of which the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawing, in which- Figure 1 represents a plan view, Fig. 2 an end view, Fig. 3 a longitudinal vertical section, and Fig. a a transverse vertical section.

The nature of my improvement consists in an improved apparatus for cooling water used for the condensation of vapor from vacuum pans in the manufacture of sugar or for the condensation of steam in steam engines.

The improvement is particularly applicable in those sections of country Where water is scarce as by means of this improvement the same water may be employed for condensation, then cooled and again employed any number of times in succession.

To enable others skilled in this branch of art to construct and use my improvement I will describe more particularly its construction and mode of operation.

A is a room 12 feet square and not less than 10 feet high; this room is filled with a series of vertical board partitions b I) the boards being rough or corrugated with horizontal seams. Between the partitions there are pasages c, c of about two inches wide. At the top of the room about 2 inches above the partitions and in line with them are a range of horizontal pipes (Z, (Z. These pipes open into a tank E containing the water to be cooled. These pipes have a ,row of fine holes along their lower side for the escape of the water. The water then passes directly on to and slowly trickles down the board partitions. The upper edges of these partitions is sharp, so as to divide the water and cause it to pass equally over both sides of the partition.

F is an ordinary centrifugal or rotary fan blower discharging its air into the upper part of the cistern H. This cistern H is entirely closed except at the interstices between the board partitions 0, 0, 0.

The operation of my improved refrigerator is as follows: The water to be cooled is pumped by any ordinary means into the tank E. From this tank it flows through the pipes (Z, (Z and escapes through the series of holes in their lower side, trickles slowly in very thin streams down the rough or corrugated surface of the boards Z), 6, and finally discharges from the lower end of the boards into the cistern H. The air discharged by the fan blower F is forced to pass from the cistern up through the interstices 0, c, as shown by the arrows, and then escapes between the pipes (Z, (Z above. This air is divided into currents by the partitions, and is forced to pass in close proximity to the attenuated streams of water trickling down along the surface of the boards. Hence a rapidi evaporation and consequent cooling of the water results. A single pasage of the water down the partitions cools it sufliciently. The boards I), Z), instead of being arranged vertically as indicated in the drawing may be placed in an inclined position the interstices being preserved.

Heretofore fan blowers have been applied to cooling water by causing the water to be dropped from an elevated tower through an ascending current of air from a blower;

, but that mode is objectionable, inasmuch as the size of the drops are not suflicient-ly attenuated to be thoroughly cooled; second, the contact of the air with the water is not sufliciently intimate, much air passing out withoutproducing evaporation, and thirdly the construction of towers of considerable elevation is required. The last is a very serious objection on account of the trouble and expense involved in the erection of towers on sugar plantations and in situations in which refrigerators are generally employed. These towers are required to be about 40 feet high, whereas by my apparatus a structure 10 feet high is amply sufficient. Moreover it will be readily seen that 10 Water, but

lVhat I desire to claim and secure by Letters Patent is- The arrangement of the series of partitions and interstices for cooling Water in the manner and for the purpose substantially as herein set forth.
